.Application led uly 3 1901.

To @ZZ whom, t r11/Cty concern:

Be it known thatwe, CHARLESB. TOWERS, a resident of Miles City, andWALTER A. CAMERON, a resident ofStacey, in the county of Custer andState of Montana, citizens of the United States, have invented a new andImproved Copy-Holder, of which the following is a full, clear, and exactdescription.

The object ofthe invention is to providea means for indicating to astenographer a particular line of manuscript from which the copy isbeing taken. It provides means for automatically operating an indicatorby the type-writing machine or for manually operating it by means of acrank, and also an automatic means for returning the indicator to thetop of the copy-holder on which it is located, thereby saving the timeand labor of the stenographer using the invention.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and the pointed out inthe claims.

Reference isdto be had to the accompanying drawings, forming a part ofthis specitication in which similar characters of reference indicatecorresponding parts' in all the views.

Figure lisa top View of our invention. Fig. 2 is a side View of thesame. Fig. 3 is detail view of the supporting means for the copy-holder.Fig. isa side view of aspringclamp for the manuscript. Figo is asectional side view of the indicator-operating mechanism shown inFig. 1. Fig. G is aseotional view on the line c a of Fig. 1 looking inthe direction of the arrows. Fig. 7 is a detail sectional view of theratchet-and-pawl mechanism which operate the crown-wheel shown inFig. 1. Fig. S illustrates the application of the invention to atype-writing machine, and Fig. 9 is aplan showing a modiicationhereinafter more fully described.

The copy-holdeuframe 1, which may consist of wood or metal, carries aworm 2 by means of brackets 3, located at either end of said worm.Movable along the worm by its rotation is a block 4, which carries apointer 5. 4 To the lower end of the worm 2 is fastened a pinion 6, sopositioned as to be operated upon by the crown-wheel 7, which hascrown-teeth 8 located on its periphery. Also located on the crown-wheel7 are ratchetteeth 9, which by the operation of the pawl Serial No.68,193. (No model.)

1 l, (shown in Figs. 6 and 7,) carried by the arm 12, causes l[herotation of the wheel 7, which in turn by the pinion 6 causes a movementof the pointer 5 along the copy-holder. The crown-wheel may be supportedby ball-bearings located in a ridge of the hub, which may be supportedby the frame-supporting mechanism. The pawl 11, which is fastened to thearm l2 by the staple 14, has a pin 15 located on its under side, whichmakes contact with the frame portion 16 and causes when in such aposition a lifting of the pawl 11 from the ratchet-teeth 9 and when awayfrom such position permits the pawl 11 to operate upon the ratchet-teethto cause rotation of the wheel 7. Also carried by the supporting-frame17 of the wheel 7 is a spring 18, which is fastened to the frame and atone end operates upon the arm 12 to keep it normally swung to one side,so that the pawl 11 will be kept clear of the rack, as described above.

The arm 12 has a slot 19, (shown in Figs. G and 7,) through which passesthe guide 20. The arm is loosel57 pivoted upon the shaft 21, whichsupports the crown-wheel 7. Firmly attached tothe shaft 21 is a crank22, by means of which the pointer 5 may be returned -to the top of thecopy-holder when the arm 12 is in its normal position and the pawl 11raised clear of the ratchet-teeth 9. Also attached to the shaft 21 andthe supportingframe for the crown-wheel (see Fig. 9) is a spiral spring'23, which may automatically perform the same operation that isaccomplished by the crank 22 when the pawl 24, which is supported on theframe b' by the pivot 25, is lifted clear of the ratchet-teeth 9 by thelever 26, which is pivoted to the side of the copy-holder at 27 and isconnected to the pawl 24. The spring 23 is wound up by the operation ofthe arm 12 as the pointer 5 passes down the length of the copy-holder,indicating each individual line upon each swing of the arm 12, and whenthe pointer has reached the last line of the manuscript the lever 26 ispressed down and the pawl 2-1 lifted clear of the ratchet-teeth 9, andthe wheel 7 is caused to return by the operation of the spring 23,carrying the pointer again to the top of the manuscript.

Connected to the swinging arm 12 is an adjustable arm 30, which has anextension 31,

to which is fastened a thumb-pin 32, movable in a bayonet-slot 33,located in the adjustable arm 30. When the extensible portion 3l ispushed downward by the thumbpin 32, said pin strikes at the bottom abent spring 34, (see Fig. 1,) which causes the pin to move into theright-angular portion of the slot 35. (Shown in Fig. 5.) When in thisposition, the rod 3l is in line with a pin located upon the adjustablemounting 36, which is fastened, by means of a screw 37, to some movableportion, as 38, which moves back and forth with the carriage of thetype-writing machine 39 and at theend of such movement causes theoperation ofthe arm 12,which is swung to the right a sufficient distanceto cause a one-step movement ora one-line movement of the pointer 5. Thedistance of this step is regulated by the position of the pinsupport 36upon the carriage of the typewriter.

Supporting the copy-holder on the framework of the type-writing machine39 is a pair of hinged rods 40 40, which are clamped tosupporting-pieces 41 41 by the clamping-rod 42, which has at one end ahead 43 and at the other end a nut 44. Thumb-screws 45 45 are employedto fasten the hinged support to the copy-holder. This permits offastening the copy-holder at any angle and also, by means oftheadjusting-arm 30, which is fastened to the swinging arm 12 by the bolt46, permits the mechanism to be operated in any position that thecopy-holder may be placed.

When the copy-holder is to be used free of the machine and is to besupported on a desk, a hinged support 50, adjustably connected to a pairof limbs 51, is located Aon the back of the copy-holder.

At the top of the copy-holder is provided a spring-clamping device 52,whichis held normally against the copy-holder by the spring 53 or anysuitable spring, which is connected to the clamp by the rod 54. At thetop of this clamp is located an arm 55, by means of which the clamp 52may be raised and the paper inserted underneath said clamp. The space atthe top of clamp 52 may be used to insert the pages after copying, asinthe case of a stenographers copy-book, duc. At the bottom of thecopy-holder may be located a pair of well-known spring-clamps 56 56 forholding the bottom of the manuscript. These spring-clamps 56 may beadjustably positioned by means of the thumb-screws 57 57 and providedwith slots in the usual manner.

Since the movements of a carriage are not in themselves uniform, andsince theamount of manuscript in several lines of a written page is alsonot uniform,the operator should after finishing the wording of each lineshift the carriage to its extreme limit, so that the movements of theindicator will be commensurate with full lines and will be uniform. If,owing to irregularities of the wording of different lines of themanuscript, the indicator tends to direct the eye of the operator ofgear at any moment and readjust the same so that the indicator will restadjacent to the line to be copied. Almost any manuscript will runapproximately With the type-written copy thereof for a few lines at atime, at least. In this event, even should the indicator be one, two, oreven three or four lines amiss, the device will notwithstanding be ofsome service, because it will at least guide the eye of the operator tothe top, middle, or bottom of the page to be copied, and this servicealone is of some utility. Even should the operator neglect to adjust theindicator along at intervals the indicator will still be of some servicefor the reason that the operator will observe to what extent theindicator is drifting away from the manuscript-lines as they are copied.y

Having thus fullydescribed ourinvention, we claim as new and desire tosecure by Letters Patent 1. In a line-pointer mechanism, the combi-Ination of an indicator, a crown-wheel and worm for moving saidindicator, means for actuating said crown-wheeland worm, a rack mountedon said crown-wheel, a swinging arm provided with a pawl for engagingsaid rack for causing a step-by-step movement of said indicator, andmeans for intermittentlyactuating said arm.
